Question

who is Newland? ....... ​

Answer 1

Answer:

Newlands was a scientist who increases our syllabus by trying to make a periodic table to classify elements according to their atomic masses. he found that every eighth element had properties coinciding with the first one. thus he named it Newlands law of octaves(8 notes in music)

Answer 2

$\huge{\blue{\boxed{\boxed{\boxed{\pink{\underline{\underline{\red{\mathscr{Answer}}}}}}}}}}$

John Newlands, in full John Alexander Reina Newlands, (born November 26, 1837, London, England—died July 29, 1898, London), English chemist whose “law of octaves” noted a pattern in the atomic structure of elements with similar chemical properties and contributed in a significant way to the development of the periodic law.

BORN ― November 26, 1837, London, England

DIED ― July 29, 1898 (aged 60), London, England

SUBJECTS OF STUDY ― law of octaves & periodic law

Newlands studied at the Royal College of Chemistry, London, fought as a volunteer under Giuseppe Garibaldi for Italian unification (1860), and later worked as an industrial chemist. In 1864 he published his concept of the periodicity of the chemical elements, which he had arranged in order of atomic weight. He pointed out that every eighth element in this grouping shared a resemblance and suggested an analogy with the intervals of the musical scale. The “law of octaves,” thus enunciated, was controversial at first but later was recognized as an important generalization in modern chemical theory. Newlands collected his various papers in On the Discovery of the Periodic Law (1884).
